Kent County sheriff's authorities and Plainfield Township firefighters were called to the scene at 4:47 a.m. after a passerby called 911 to report a vehicle had struck a tree along Jericho Avenue and a person inside was not responsive, according to dispatch traffic.

There were no reports of anyone else in the vehicle. It's not known when the crash itself happened.

Kent County dispatchers say Jericho Avenue remains closed at 6:30 a.m. May 21 between Peter Creek Drive in Plainfield Township and James Street in Rockford. Jericho turns into Oak Street in Rockford, and intersects with James Street there.

Jericho also intersects with Kroes Street to the south, so traffic to Rockford High School may be impacted.
